### FAQ

#### Is a PMP certification worth it?

A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations.

#### What are the best certifications for project managers?

The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation.

#### How does PMI support career growth for professionals?

PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers.

#### What is the PMBOK® Guide?

The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery.

#### How is AI changing project management?

AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment.  PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes.

#### What are the most important skills for a project manager?

Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates.


#### How can I get involved with the PMI community?

Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections.

#### What is the difference between PMP and CAPM?

The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification.

#### How does PMI support social impact?
PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world.

 When an expert witness takes the stand to testify, he is a courtroom performer with an important privilege. Other witnesses are allowed to deal only with facts they have observed; the expert is often there to present his opinions and conclusions as well. At the trial of Jack Ruby, the experts had a field day.

Actually, as District Attorney Henry Wade explained afterward, the real expert witness in the Ruby trial was not a specialist but a policeman. The prosecution clinched its case by showing premeditated intent: Ruby, so the officer testified, had said: “I hope I killed the son of a bitch! I intended to shoot him three times.”

It was Defense Attorney Melvin Belli who needed the expert witnesses, for Belli based his case on the argument that Jack Ruby was insane when he shot Lee Harvey Oswald. Belli produced a clutch of top psychologists and psychiatrists, all of whom testified that they had found something mentally or emotionally wrong with the defendant. The prosecution brought in its own squad of equally expert professionals, who testified to the contrary. Rebuttal was met with counterrebuttal and the witnesses were cross-examined till they were crosseyed. At the last minute, Belli put in a rush call to Chicago, persuaded Neurologist Frederic A. Gibbs—who had been reluctant to testify—to fly immediately to Dallas to help the defense. Gibbs got on the stand and said that Ruby was a victim of psychomotor variant epilepsy, characterized by “lack of emotional control—impulsive and obsessive types of behavior.”

District Attorney Wade and his assistant William Alexander had a few other experts waiting in New York, but never felt it necessary to call them in. Their own counterexperts had performed extremely well. As for the rest, Wade and Alexander merely made their most telling points by demolishing opposition witnesses one by one.

Parolee & Physicist. The Ruby trial was a prime example of the problem expert witnesses pose for the jury—the often agonizing choice amateurs must make between the opposed opinions of two squads of specialists. With the use of expert testimony becoming commonplace in many kinds of cases, the battle of the experts and their rival qualifications is often decisive. An expert may be anyone from a paroled moonshiner to a nuclear physicist: what matters to the law is that he testifies about things that are peculiarly within his professional province.

What matters to lawyers, in addition, is the effectiveness of the expert’s presentation to the jury. Not all experts, to be sure, will have the shock value of the legendary Perry W. Fattig of Atlanta. A shy entomologist, Fattig practically made a second profession of taking the stand when soft-drink bottlers were sued when bugs were found in their beverages. Expert Fattig would explain that eating an insect could be harmless, then he would plop a live roach in his mouth and chew it up. The demonstration was invariably impressive, but most trial lawyers agree with San Francisco’s Jake Ehrlich, who looks not for stuntmen but for experts with “a pleasant demeanor, good solid judgment, some learning, and the sense to keep quiet at the right time.”

Art at Length. To permit an expert to give an opinion even about facts that he has not personally observed, lawyers make a fine art of constructing that curious type of question called “hypothetical.” In such questions, every relevant fact in evidence is put to the witness at length, as if it were all some imaginary problem. In what may be the champion hypothetical question of all time, a California lawyer defending his handling of an estate asked another lawyer serving as an expert a whopper that ran to 83 pages of trial transcript and 14 more pages of defense objections.

Experts not only get more leeway than other witnesses, they also get paid. Fees may run from $100 to more than $300 a day, plus expenses. Doctors and psychiatrists may pull down $50 an hour on the witness stand, along with their fee for pretrial examinations and tests. In the Ruby trial, Guttmacher and Schafer are getting about $1,000 each. Such fees take into account ex tensive pretrial preparation; but as Atlanta Trial Lawyer Charles D. Read Jr. pointed out: “A real fine expert comes high.”

“It takes only a little know-how to buy an expert who happens to represent the right view” is the cynical observation of one Washington, D.C., law professor. Most trial lawyers would agree to the fact, but not necessarily to the cynicism. Particularly in such fields as psychiatry, where theories, methodology, and even terminology are far from settled, the diametrically opposed expert opinions brought out in a trial are likely to be rooted in genuine professional differences. But the ability to make a choice between those differences is one of the cornerstones of U.S. justice. When experts cannot agree, the final decision is made by twelve men, good and true.
